PROBLEM TO BE SOLVED: To provide a vehicular seat with a built-in cushion airbag device capable of reducing a load on the neck of a seated occupant while ensuring restraining force applied to the waist upon a frontal collision.SOLUTION: A cushion airbag 30 is set such that push-up force in rear left and right regions A1 and A3 corresponding to ranges from hip joints P2 to ischium lower parts PS on the left and right of a seated occupant P in an expansion completion state is smaller than push-up force in a rear central region A2 between the rear left and right regions A1 and A3 in the expansion completion state. As a result, while the push-up force of the cushion airbag 30 is applied toward a recess part between the ischium lower parts PS of the seated occupant P, the ranges from the hip joints P2 to the ischium lower parts PS of the seated occupant P are not strongly pushed up.SELECTED DRAWING: Figure 3
【課題】前面衝突時における腰部の拘束力を確保しながら着座乗員の頚部への負荷を軽減することができるクッションエアバッグ装置を内蔵した車両用シートを得る。【解決手段】クッションエアバッグ30は、膨張完了状態における着座乗員Pの左右それぞれの股関節P2から座骨下部PSまでに対応する後左右領域A1、A3における押上力が、膨張完了状態における後左右領域A1、A3同士の間である後中央領域A2における押上力よりも小さくなるように設定されている。したがって、着座乗員Pの座骨下部PS同士の間の凹状部分へ向けてクッションエアバッグ30の押上力が作用する一方で、着座乗員Pの股関節P2から座骨下部PSまでの範囲は強くは押し上げられない。【選択図】図3
